Understanding the complexity of knowledge integration in collaborative new product development teams: A case study

Knowledge integration is important in collaborative new product development (Co-NPD). The research literature shows that the way actors create a shared understanding about the new to create products is a quality indicator of Co-NPD. This study investigates what factors influence the creation of a shared understanding in Co-NPD. The results show factors at three different levels; the actor, project and company level. Additionally, there exist relationships across the factors. The related factors form four different types of interfaces. The interfaces differ from each other since different types of collaborative mechanisms exist within them.     

Parental Divorce,Residence Arrangements,and Contact Between Grandchildren and Grandparents

When parents divorce, grandparents can play a supportive role in the lives of their grandchildren, but a parental divorce may also put grandchild–grandparent ties under pressure. In this study the authors investigated how grandchildren of married and divorced parents differ in the frequency of face‐to‐face contacts with grandparents and how this is mediated by postdivorce residence arrangements. Based on the multi‐actor survey “Divorce in Flanders,” they used reports of contact provided by more than 1,000 grandchildren and compared them with more than 1,100 grandparent reports for validation. The results showed that grandchildren from divorced parents have fewer contacts with their grandparents than grandchildren whose parents are married but that it is the postdivorce residence arrangement of grandchildren that produces this result. When grandchildren live with their divorced father or in a shared residence arrangement, they even see paternal grandparents more often than grandchildren with married parents.     

An Explorative Study of the Place of the Ethics of Care and Reflective Practice in Social Work Education and Practice

The moral development and identity of social work students have been shown to be enhanced by education in caring. Important aspects of this education are training in reflective practice and learning to have a perspective focused on professional loving care. In this study, we have explored how reflective processes can be implemented in both educational settings and working practice from an ethical point of view. Elaborating upon reflective practice from an ethical perspective focuses on reciprocity in relationships and relational capacity in institutional contexts. The study took the form of interviews with social work teachers and health care professionals. Interview and focus group data were analysed, three main topics were identified and statements were coded with relation to these topics. Use of both educators and practitioners in this study showed the importance of not neglecting the transition from education to practice. Responses also showed the value placed upon continuous education and development over the course of a health care professional's career.

Abstract

This study investigates three methods to handle dependency among effect size estimates in meta-analysis arising from studies reporting multiple outcome measures taken on the same sample. The three-level approach is compared with the method of robust variance estimation, and with averaging effects within studies. A simulation study is performed, and the fixed and random effect estimates of the three methods are compared with each other. Both the robust variance estimation and three-level approach result in unbiased estimates of the fixed effects, corresponding standard errors and variances. Averaging effect sizes results in overestimated standard errors when the effect sizes within studies are truly independent. Although the robust variance and three-level approach are more complicated to use, they have the advantage that they do not require an estimate of the correlation between outcomes, and they still result in unbiased parameter estimates.     

A SNP,Gene, and Polygenic Risk Score Approach of Oxytocin‐Vasopressin Genes in Adolescents’ Loneliness

Not much is known regarding underlying biological pathways to adolescents’ loneliness. Insight in underlying molecular mechanisms could inform intervention efforts aimed at reducing loneliness. Using latent growth curve modeling, baseline levels and development of loneliness were studied in two longitudinal adolescent samples. Genes (OXTR, OXT, AVPR1A, AVPR1B) were examined using SNP‐based, gene‐based, and polygenic risk score (PRS) approaches. In both samples, SNP‐ and gene‐based tests showed involvement of the OXTR gene in development of loneliness, though, significance levels did not survive correction for multiple testing. The PRS approach provided no evidence for relations with loneliness. We recommend alternative phenotyping methods, including environmental factors, to consider epigenetic studies, and to examine possible endophenotypes in relation to adolescents’ loneliness.     

Fairness judgments in household decision making

The behavioral economic study of fairness was applied to household decision making. A sample of household partners judged the fairness of a number of hypothetical decisions of a household partner, varying in the context of the decision. Decisions made by the partner to make a large personal expenditure or to reduce time spent on household chores were considered by the subjects as more fair if the outcome was framed as a forgone gain then if it was framed as a straight loss. Partners’ decisions to reduce household chores were also considered as more fair in the case of overtime work than when the partner received a salary increase or windfall income. We conclude that asymmetric valuation of losses and forgone gains, and (behavioral) costs as compared with income increase of the partner, influenced the fairness judgments concerning the partner’s behavior.     

Children’s Relationships With Grandparents in Married and in Shared and Sole Physical Custody Families

ABSTRACT

Grandparents can be an important source of support for their grandchildren in the often difficult time during and after parents’ divorce or separation. Grandchild–grandparent relationships can be hampered or even totally lost when parents separate, however. What happens with grandparent relationships when parents break up is closely linked to postdivorce physical custody arrangements. This article focuses on the beneficial role that grandparent relationships can play after parents separate and examines how grandparent–grandchild relationships differ in shared and sole physical custody arrangements.
